IMPROVEMENT IN SELF-ACTING JACKS FOR SPINNING.

The Schedule ,referred to in these Letters Patent Vand making part of the same.

I, PETER MCGGVERN, of Lawrence, in the countyy f of Essex and State of llztssachusetts, have invented certain Improvements in Jacks for Spinning, of which the following is a specification.

Myimprovements relate more particularly to the construction ofjacks for spinning wool which are what is called self-acting, in which the several operations in spinning are performed automatically, by which the mechanism is sirnplied and adapted to be applied to jacks already constructed to work by hand without great alterations, and to be worked by a single driving-belt applied to the main driving-shalt of the inachine.

As the several points of improvement relate mainly to the manner of constructing and arranging the subordinate parts of the machine they will severally be explained in connection with their description.

Description.

In the drawing- Figure 1 is an elevation of one end of the machine;

Figure 2 is an elevation of the back side;

Figure 3 is au elevation of the front side of the carriage and mechanism at that side of the machine;

Figure 4 is a plan of the machine;

Figure 5 isa transverse vertical section and Figures 6, 7, 8, and 9 are details that will be referred to in the description.

1n the following description that side of the machine at which the driving-gearing is situated will be called the back side, and the Vopposite side the front or forr ward side, and those parts of the machine which are old and not modilied by my improvements will be merely mentioned hy name Without further description.

A is the frame-work of the machine.

B is thc carriage, mounted upon carrying-wheels B, which run upon the rails A', attached to the frame or otherwise.

C C are the spindles driven from the drum D, all in the usual way.

E E are the 4roller-jaws, and

E F are the drums to carryithe bobbins of roping,

connected by gearing, as shown, and driven by the inclined shaft G from the shaft H, with a countenor clock, I, to throw the shaft Gout of gear to determine the delivery ofthe roping, Iall in a well-known manner.

J is the driving-shaft of the machine,. which carries the driving-pulley K-fast upon it, and the pulley K1, which runs loosely upon it, having a long huh or quill, which, upon the outer end, carries the pinion L and the loose pulley K2, which runs loosely upon the outside of the hub of K to stop the machine.

The shaft J alsocarries the friction-clutch cone M,

for backing off, the race-pulley Ml for driving the spindles, andthe pinion M2- for driving the train of gearing by which the carriage 1s drawn ont, the roping delivered, and the carriage drawn in to relieve the twist, all of which are fast upon it; and the gear M3, havinga hollow cone which works with the cone M to backloii, which runs loosely upon the shaft J and engages with the gear N, which runs loosely upon the shaft O, and which, by the clutch il', carries the shaft O and scroll O', by which the carriage is run in.

The pinion L through the intermediate gear LI carries the gear L2 on the back shaft P, upon the opposite end of which is the pinion l, which engages with the gear M3 and furnishes the motion to back oi' and run -in the carriage from thepulley K.

The pinion M2 engages with the intermediate gear M", which carries a pinion, M5, that engages with the gear Q, -which, by means of the clutch Q, drives the scroll E upon the shaft R, which draws ont the carriage by the cord E2, as is shown.,

The gear Q runs loosely upon the shaft R, and to it is attached the worm Q2, which works in a small wheel, T, upon the top of the vertical shaft T1, which,

by the clutch T2, drives the pinion T, that runs loosely on the shaft at the bottom and works in a rack, S, on the long rod S', which reaches nearly to the front of the machine, and is provided with a gab or hook, b, which engages with the pin aupon the carriage, as will be described, and thereby draws in the carriage a short distance during the putting in of the twist to compensate for the shortening ofthe yarn.

U is a bent lever for working theclutch Q1, the horizontal arm of' which rests atA its inner end upon an incline upon the back end of the slide/V.

The forwardeiid of the slide is jointed to the lower aim of the bentlever V1, which works the clutch-T2.l

To this arm also is jointed the long rod V2, which operates both the clutch and slide and reaches to the front parthof the machine. lts front end is provided with an arm or'hook, Vi, upon its upper side,`which engages with the pin-a upon the carriage, by which the rod V2 is drawn forward at the last part of theoutward movement of the carriage, and thereby drawing the incline upon the slide V under the arm of the lever U, raises it and `throws out the clptch Q and stops the drawing-out scroll R, and also, by the same -movement, throws into engagement the clutch T2 of the `drawingin mechanism. Y

This rod is pushed back by the bracket IB2 upon the carriage, coming in contact with the arm V upon'the rod Vz at the last part of its inward motion, which thereby pushes back the slide V and-removes the inoline from beneath the arm of the lever U., and allows it to fall'by gravity and the force of the spring U', ywhich throws the clutch Q into gear, and at the same time, bythe bent lever V1, throws the clutch T2 out of gear, putting the parts in a condition to commence the draft. v

W is the shipper-shaft, which controls the movements of the mechanism foxrunning in and stopping `the carriage and the backing ofi'. 'It is set vertical, and has at the bottom near the door the arm WI and a stii leaf-spring, W2, attached to it, as is shown.

-Next above this is the forked armI W, that slides the gear M3 on its shaft.

vAbove this is the forked .arm W@ that slides the `gear N. p

Above this is the double arm W5, which co-operates with the latchX, which is controlled by the twistcounter or clock X.

The outer end of the arm NV1 and spring JW are embraced by two stops, Y1 Y1, upon the long rod Y, which extends to the front of the machine. Its back endis suspended upon the lower end of the bent lever Y, the other arm of which, toward the carriage, is curved downward, so that the carriage when it runs t in slides over the lever and depresses it, drawing back the rod Y against the teusionof the spring Yi, which draws the curved arm of the lever Y up\vard.

Before the carriage begins to depress the lever Y the arm Wl will be engaged with the hook of the detent or latch Ys, which is in the form of a bent lever, asis shown, and its catch is forced upward toward the varm WV* by the coiled springY6 uponI its axis. This holds the arm Wl fast while the depression of thev lever Y by the carriage draws the rod Y back, bending the spring W2 until a catch upon the forward end of the i rod falls below its bearing in the standard in which it slides, which locks thev rod -and prevents it from returning, thus setting the spring W and preparing it foritstuture action, as will be described.

The clock or counter' X is mounted upon a slide, vX1,in the usual manner. It is raised by means of the lever X2, having an .incline upon its upper side at its forward end, upon which the carriage acts to de press it at the last part of vits inward motion. This arrangement gives a much easier movement to both the slide and carriage than that usually adopted for' that purpose. f

` Upon the iuside of the slideX1 is lxed a stud, c, I

whichworks in a'slot in one arm of the latch X, and also engages with the horizontal arm of the shipper Z. This engagement is by means of a rod with a. shoulder below, which extends up through the studc some disvtance and has a spiral spring, c', upon it, which rests up- 0n the stud and has a collar above-itiniadefast to t-he rod. By this ,means the shipper may he moved-foutward to throw the belt onto the loose pulleyl2 to stop the machine by compressing the spring c' \`vith out moving the slide X1.

Upon the inner side of the shipper, toward the front, is fixed a bent arm, X, which is operated by the swinging arm X5, which is mounted upon a shaft, s, upon the carriage.

To the opposite end of this shaft is attached au upright arm, t, the top 'end of which is connected with the long rod u, which extends the yentire length of the carriage. Y

' Whenl the machine isat work the arm X5 is swung upward so as to pass over the arm X4 on the shipper and not come in contact with it; but when the opel'- ator'desires to stop the machine, by sliding the rod u lengthwise to the left the. arnr X5 is lowered so as to come in contact with the bent arm X* and crowd the shipperlaterally so as to throw the belt onto the loose pulley K2 and stop the machine in the proper position tolmend up-that is. a little before it finishes its in-V ward motion. A

When the machine is toxhe started the rod u is drawn in the opposite'direction, which swings the arm X5 out of contact with the arm X, and allows the spring c' to move the shipper to the position tolead the belt onto `the pulley K, and continue the operation of the machine. i f

An arm upon the lower end of the shipper Z is extended down near'the iloor,'and against the inner side of this the long-lever X, which lies upon the floor, works. This lever has its fulcrum ynearthe middle, and extends to the front of the machine, as shown. v

By means of this the'belt may be thrown oi' at any time by the operator, the 'spring c'f upon the shipper permitting such action, and the lever is held in that position by the catch X upon the door.

are gears R2. and O2, which are connected by two intermediate gears. The gear O2 runs loose upon its shaft, and is connected therewith by a coiled spring inclosed in the box Oi. The purpose of this arrangement is to' use two cords only with single scrolls to work the carriage, by which the winding up of one cord will unwind theother, the cords being kept tight on the scrolls by the tension of the coiled spring in the box O5. `But this arrangement is not ot' my invention.

On the carriage is au arm, d, which strikes against theshipper-arm W5 andy insures the throwing out of the drawing-in. clutch N on the gear N when the car- The chain j', which operates this drum, is attached to a sliding block, kl, ou the radial arm k, which hangs upon a bracket, ki, upon the.carrage, as shown, and is provided with fa screw, l, and gearing to operate the block in the usualway, excepting as will be described. The radial arm'k'earries a roller, k, which works on thehup'per surface ot' a' long curved bar, m, to give the requisite motion to the arm as the carriage runs back and forth.v v

This har and the arm are so arranged `rand the cooperating parts are so proportioned to each other that the bar can be placed bencaththe carriagewithont `any modification of the carriage from its usual coustruction 'in a hand-jack. Thisis a matter of great importance in converting a hand-jack into a self-acting jack.

The screwil, seen more clearly in ugs. S 'and 9, is operated'byV a pair of bevel-gears, l1, at the bottom, to

--the axis o'f one of'which is attached-a small spur-gear,

The lever l* is suspended by the chain 'm2 from the arms el and f" cf the faller and counter-faller, respectively, so that, when the 'winding-on is too fast, the counter-faller is-drawn down by the yarn and lowers v the gear l3 so that it will engage'with the rack m as the carriage runs in and through the gearing just described, turn the screw l, and adjust the block in the usual way. y y

B2 is a bracket, which is secured to the under side of the carriage B, extending downward neariy to the door. To the lower end of this is jointed the horizout-al arm nl, the opposite end of which carries the long stud n, and is suspended by thef rod n from the arm oI of the rocker-shaft o.

The rocker-shaft ois mounted upon theeiuside of the carriage B, and has another horizontal arm, o2, and a vertical arm, o.

The arm o2 at its outer end carries the grooved rollerp, and the arm o at its lower end is, by the connecting-rod p, attached to theplateh-rod 112, which leads up to an arm, e, on the taller-shaft e, to operate the 'aller. s

The rocker-shaft o is operated by the chain q', one end ot' which is attached to the arm e" on the tallershaf't e, and the other' end is wound upon` the pulley q', which runs loosely upon the drum-shaft D', and is i'ng raised, as described, so that the carriage can be run in without disturbing the rod. It also draws iorward the. rod V2 to throw out the running-out clutch Q and throw in the drawing-in clutch T2. It also raises and unlatches the front end ot' the rod Y to allow the spring Y4 to throw it forward, moving the shipper W so as to disengage the ii'iction-clutch M and stop the backing-olf.

fr is the copping-rail, upon which the stud r runs to operate the fallcr e and shape the cop. This lst-ud is secured in the eudof the swinging arm r2, the opposite end of' which is jointed to the bracket fr, which is attached to the under side ofthe carriage, as shown.

lhe stud r1 extends out suiciently to engage with the latch or shoulder p3 ou the lower end ot1 the latchrod p2, by which the faller is moved.

The mechanism shown, by which the copping-rail is raised and lowered, is not materially ditferent from what has been before used for that purpose.

s1 is a bracket, which is attached to the underside of the carriage and carries the stud s, which, as the carriage runs ont, raises the latch s3 from the pin sf to disengage the rod V2 and allow itto be drawn forward, and also works the lever S5, wluch operates the ratchet that lowers the copping-rail.

,L1 is a brake-strap on the drum j, which is worked by the bent lever t2, which is in turn worked by the lower end of thel bracket t2 to tighten it.

al is a cord wound upon the drum j to wind on the chain'j, and which is led ba'ck around pulleys to aA convenient place and attached to the weight fw, which operates it in the usual way.

Upon the counter-taller shaft is ixed a sector, f3, upon which a chain works which is attached to the vertical` rod y, which leads down 'to the lever y1.

On the lower extremity of this level' is a roller which runs under the fixed cams y2 and y, attached to the iioor, and prevents the rising ot' the counter-taller unduly at `the time ot' backing oli', and running up the yarn to the points of the spindles. l i

Upon the taller e is a locking-arm, e, which swings over a shoulder, 1 4, on therod y, and holds the counteri'aller froin risingr too high while the draft' is being made, but leaves it free while windingon the yarn.

rlhe counter-taller is held up by the sector f* and chain leading to the lever 1/5, which is weighted sulficicntly for that purpose.

Some of the parts shown are not described, as they are substantially' suoli as have been used before.

The mode of operation ofthe machine is as follows:

Let the carriage be supposed to be run in to thc pov sition for winding. up the yarns and the machine at rest, the driving-belt running upon the'loose pulley K2, being held there by the arm X5 on the carriage, which acts upon the arin X* upon the shipper Z, as has been describeda To start the machine the operator, by sliding the rod u', swings the arm X5 upward ii'orn the arm X4, which leaves the shipper at liberty to swing inward by means of the, spring c', on the rod connecting the shipper with the clock-slide Xl, which throws thc belt upon the pulley K1 to complete the operation nl" running in the carriage.

During the last part ofthe movement the carriage will have passed over the lever Y, depressing it, and drawing back the rod Y andstops Y1 until the shoulder at nf* drops below the slot in the standard n3, as seen in tig. 6, which locks the rod.

This action oi the rod Y compresses the spring W" on the arm W1, because the catch or detent Y5 prevents the arm W1 from swinging outward. At this` time, also, the roller h will have raised the lever It', which puts the shaft G into gearwith the shaft H audits counter I, ready to deliver the roping; also, the lcv-er X2 will be depressed at its iunercnd to raise the clock-slide X to put the clock or counter Xinto gear with the wornl-shaft H, and to move the shipper Z s0 as to throw the belt onto the pulley K; also, the lowerend of the bracket B2 will strike the arm V3, ou the rod V2, pushing it forward and removing the incline upon the slide V from beneath thc outer end of the lever U, which. allows it tovfall and4 bring the clutch Q into engagement, ready i'or running out the carriage. At the extremity of its movement inward the carriage Astrikes the upright arm of the catch or deten-t Yf, depressing the hook from the arm W of the shipper-shaft, which instantly flies back until the short arm of W5 strikes the detent or latch Xpturning the shipper-shaft sufficiently for the arifn'Wfto disengage the running-in clutch i But in case the spring W2 should tail to operate the shipperand disengage the clutch N', the armd, on the carriage, would strike the long arm of lV and force it backL turning thc shipper-shaft so as to disengage the clutch.

As soon as the driving-belt has run upon the pulley K the outward movement of thecarriage commences driving the spindles by the pulley' Ml and the runningout scroll R, and the delivery of the roping by the gear M5 and the trains of gearing which it drives.

When the carriage has reached nearly its outer limit the stud a comes in contact with the stop a5, on the upper side ot' the rod V2, and draws the rod forward and with it the slide V, at the opposite end, bringing the vincline upon the slide under the end ot' the shipping-lever U, which raises it, and throws the clutch Q1 out of gear and stops the carriage.

vThe same movement of the rod V2 operates the shipper-lever V1 and throws the clutch- 'li'into gear to draw in the carriage by the rod S', the gab b oi which embraces the stud a to compensate for the shortening of the threads by the twist. y

Then the requisite twist has been given the clockslide X1 is disengaged in Vthe usual way and falls, car-- rying the short arm ofthe shipper Z with it, which swings the shipper so as to throw the driving-belt onto the pulley K1, and also raises the latch X2, which restrains the short arm of V on. thcv shipper-shaft W,

and permits the spring W2 to throw the shipper-shaft far enough to throw thp gear M3, with the hollow cone, onto the cone M, engaging with it, and giving to the shaft J a motion backward to back oft the varo.

By the backward motion of the drum-shaft D' the pulley g winds 'up the chain q, pressing upward the roller p and rocker-arm 02, and draws down the taller c until thelatch-rod 11, which is'attached thereto, rises so high that the shoulder p3 will pass over the pin r1, which rests upouthe copping-rail yr. As soon as this takes place the rod pz swings inward thebreadth of the shoulder, and, by its connection with the rockershaft o through the rod p1 and arm 03, allows" the rocker-shaft and its several arms to turn a corresponding distance, which, by the arm o1 and rod ai, raises the stud it, lifting the rod Y so that its shoulder ns is natu clear of the standard n, and allows it to dart forward by the tension of the spring Y, turning the shippershaftV W, and instantly drawingyback the cone-gear' M3, stopsthe backing oil', and at the same time throws into gear the clutch N by sliding the gear N on its shaft O, which puts in operation the running-in scroll O. The carriage then runs in, winding the cop by the winding-drum, and forming it by the copping-rail, in the usual manner, until the carriage is nearly in, when the lower end of the latch-rod p2 meets a stop in the frame-work below, which withdraws the shoulderp3 from Athe piu fr and allows the faller to'rise. The machine is then in the conditionwith which the description ofthe operation commenced.

The purpose of the brake t1 upon the winding-drum j is to produce a'teusionnpou the winding-chain and its connections -by the drawing-in motion of the rod S, so that the winding shall commence instantaneouslywith the running-in motion ofthe carriage; but as soon as the carriage has moved in a short distance the bracket la? will have left the lower arm of the lever t2, whichleaves the brake free.
